What Is A Membrane Filter Press?
Compared to standard chamber filter presses, membrane filter presses incorporate a secondary squeezing step after the filtration process. Specifically, elastic membranes are installed on both sides of the filter plates; introducing compressed air or water causes the membranes to expand and exert additional pressure on the filter cake, resulting in a drier cake.
Furthermore, the arrangement of filter plates in a membrane filter press differs from that of a conventional filter press, consisting of an alternating sequence of membrane plates and chamber plates.
How Does a Membrane Filter Press Work?
Membrane filter presses incorporate a secondary squeezing stage following the conventional filtration process to produce a drier filter cake.
STEP 01
Feeding
Slurry is pumped into the filter chambers through the feed pump.
STEP 02
Filtration
Solids are retained by the filter cloth, while filtrate passes through and flows out.
STEP 03
Membrane Squeezing
Compressed air or water expands the membrane plates to squeeze the filter cake again.
STEP 04
Cake Discharge
The filter cake after the second pressing is drier and easier to discharge.

Why Choose a Membrane Filter Press?
Compared with a standard chamber filter press, membrane squeezing provides deeper dewatering and higher efficiency.
Lower Filter Cake Moisture Content
After the initial filtration phase, the diaphragm filter press uses its diaphragm plates to squeeze the filter cake, further expelling moisture and achieving a final moisture content of 30%–60%.
For High-Moisture Sludge
Standard chamber filter presses offer limited dewatering performance, whereas diaphragm filter presses are better suited for applications requiring drier filter cakes.
Easier Unloading The Filter Cake
Following diaphragm squeezing, the filter cake is more compact and structurally intact, making it easier to discharge—a feature particularly advantageous for automatic plate-shifting systems and continuous production operations.

Filter Press FAQ
A membrane filter press incorporates a secondary pressing stage following the standard filtration process. Its membrane filter plates expand using compressed air or water pressure to further squeeze the filter cake; compared to a standard chamber filter press, this method helps reduce the moisture content of the filter cake.
Can a membrane filter press reduce the moisture content of the filter cake?
Yes. After filtration is complete, the membrane squeezing process can further remove moisture from the filter cake. The moisture content of filter cake in a conventional chamber filter press is 50-75%, while that in a diaphragm filter press is 30-60%.
The squeezing pressure depends on the material properties and process requirements. Compressed air or water can be used to expand the membrane. Typically, the membrane squeezing pressure is 1.2 MPa; our engineers will recommend the appropriate pressure based on your slurry type, required filter cake moisture content, and operating conditions.
Membrane filter presses are recommended when you require drier filter cakes and higher filtration efficiency. They are particularly suitable for applications involving high-moisture sludge, fine-particle slurries, viscous materials, mine tailings, chemical sludge, and industrial wastewater treatment.
To recommend a suitable model, please provide the following information: material to be filtered, solid content, treatment capacity, working hours per day, required cake moisture, site voltage, and whether automatic plate pulling, cloth washing, drip tray, or belt conveyor is required.
